Unsettling footage obtained exclusively by NBC News shows the moments leading up to the fatal police shooting of Keith Lamont Scott in Charlotte, North Carolina.

The footage, taken by Scott's wife, does not clearly show the exact moment he was shot by police on Tuesday. Scott is seen on the ground moments after the shots were fired and surrounded by officers.

"He better not be f---ing dead, he better not be f---ing dead," Scott's wife Rakeyia Scott can be heard shouting at the police officers. "He better live, he better live!"

"He has no weapon — don't shoot him!" she is heard saying.

Police say Scott had a handgun on him and posed "an imminent, deadly threat." The family says he was not armed and did not pose a threat to the officers.

The killing of Scott, 43, sparked three nights of fiery protests and violent clashes between protesters and law enforcement. Activists and the Scott family have pressed city officials to release bodycam or dashcam footage of the fatal encounter, which reignited debates about race and policing nationwide.
